<a href="MockRequest.html"><code>Rack::MockRequest</code></a> helps testing your <a href="../Rack.html"><code>Rack</code></a> application without actually using HTTP.

After performing a request on a URL with get/post/put/patch/delete, it returns a <a href="MockResponse.html"><code>MockResponse</code></a> with useful helper methods for effective testing.

You can pass a hash with additional configuration to the get/post/put/patch/delete.
<dl class="rdoc-list note-list"><dt><code>:input</code>
<dd>
A String or IO-like to be used as rack.input.
</dd><dt><code>:fatal</code>
<dd>
Raise a <a href="MockRequest/FatalWarning.html"><code>FatalWarning</code></a> if the app writes to rack.errors.
</dd><dt><code>:lint</code>
<dd>
If true, wrap the application in a <a href="Lint.html"><code>Rack::Lint</code></a>.
